Blockchain in Voting Systems

Blockchain technology has the potential to revolutionize voting systems by enhancing security, transparency, and trust in electoral processes. This lesson explores how blockchain can be integrated into voting systems and examines real-world applications.

2.1 Blockchain

A blockchain is a decentralized digital ledger that records transactions across many computers in such a way that the registered transactions cannot be altered retroactively.

2.2 Smart Contracts

Smart contracts are self-executing contracts with the terms of the agreement directly written into code. In voting, they can automate processes such as vote counting and result validation.
